Abstract
Certain aspects of the present disclosure provide techniques for sharing uplinks in a multiple radio access technology environment. Such techniques may improve transmission and processing of acknowledgment data from a user equipment in the multiple radio access technology environment.
Claims30
A method for providing acknowledgment data from a user equipment in a multiple radio access technology environment, comprising:
- receiving, at the user equipment from a first base station, a first data transmission on a first physical downlink shared channel in accordance with a first radio access technology;
- and
- transmitting, from the user equipment to a second base station, at least one of:
- an acknowledgment (ACK) on a physical uplink control channel in accordance with a second radio access technology after determining, by the user equipment, that the first data transmission has been received correctly;
- or
- a negative acknowledgment (NACK) on the physical uplink control channel in accordance with the second radio access technology, after determining, by the user equipment, that the first data transmission has not been received correctly.
A user equipment for wireless communication in a multiple radio access technology environment, comprising:
- a memory comprising executable instructions;
- and
- a processor configured to execute the instructions and cause the user equipment to:
- receive, at the user equipment from a first base station, a first data transmission on a first physical downlink shared channel in accordance with a first radio access technology;
- and
- transmit, from the user equipment to a second base station, at least one of:
- an acknowledgment (ACK) on a physical uplink control channel in accordance with a second radio access technology after determining, by the user equipment, that the first data transmission has been received correctly;
- or
- a negative acknowledgment (NACK) on the physical uplink control channel in accordance with the second radio access technology, after determining, by the user equipment, that the first data transmission has not been received correctly.
A method for processing acknowledgment data from a user equipment in a multiple radio access technology environment, comprising:
- transmitting, from a first base station to the user equipment, a first data transmission on a first physical downlink shared channel in accordance with a first radio access technology;
- receiving, at a second base station from the user equipment, at least one of:
- an acknowledgment (ACK) of the first data transmission on a physical uplink control channel in accordance with a second radio access technology;
- or
- a negative acknowledgment (NACK) of the first data transmission on the physical uplink control channel in accordance with the second radio access technology;
- and
- transmitting, from the second base station to the first base station, the at least one of the ACK or the NACK.
A system for processing acknowledgment data from a user equipment in a multiple radio access technology environment, comprising:
- a memory comprising executable instructions;
- and
- a processor configured to execute the instructions and cause the system to:
- transmit, from a first base station to the user equipment, a first data transmission on a first physical downlink shared channel in accordance with a first radio access technology;
- receive, at a second base station from the user equipment, at least one of:
- an acknowledgment (ACK) of the first data transmission on a physical uplink control channel in accordance with a second radio access technology;
- or
- a negative acknowledgment (NACK) of the first data transmission on the physical uplink control channel in accordance with the second radio access technology;
- and
- transmit, from the second base station to the first base station, at least one of the ACK or the NACK.
